摘要：
We use a facile pyrolysis method to prepare reduced graphene oxide and copper nanocomposite (RGO/Cu) based on it. The product shows an outstanding wave absorption properties. The maximum reflection loss is up to–50.7 dB at 3.8 GHz. The reflection loss of–10 dB (90% power absorption) corresponds to a bandwidth of 11.2 GHz (3.4–14.6 GHz range) for the layer thickness of 2–5 mm. Therefore, it is suggested that the RGO/Cu nanocomposite is also a new kind of lightweight and high-performance EM wave absorbing material.
